Symmetry software for mathematics and art, for the Macintosh. A computer-aided design tool that allows you to quickly create complex two-dimensional symmetrical patterns. It simplifies the study and use of mathematical principles that underlie the regular structures found abundantly in nature as well as in products from textiles to architecture. The Symmetry Studio 1.01 package, released in 1991, and a book (with design examples and a stamp library) about it, are available for download.
